is not a disease, its a symptoms ( a kindda complaint). well diseases is yet to be found. to find the cause of jaundice one needs few investigations as your direct billirubin is higher, it could be classified as cholestatic jaundice and there are still numerous causes for it, yes the commonest would be viral hepatitis
. but for sure just that investigations cant tell you the complete story. moreover your examination is also must to see if there is other organs that are enlarged like spleen
also the color of your stool and any other skin or peripheral changes. even we have no idea of your age.
so to give u an appropriate advice its a bit vague thing to do and not a ethical thing to do
